ROTATABLE DISK CALENDAR 2 Sheets-Sheet 2 Filed Sept. 19, 1946 lfosepk {I Jus Patented Apr. 4, 1950 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to. improvements inmultiple year calendarsv of the general type havin relatively movable rotatable disc members.

An object of the invention is to provide an improved calendar of the type referred, to that will be simple in construction and in which the indicia will be so arranged that the same. will be readily understood and which may be easily set for the year desired.

A further more specific object of. the invention is to provide an improved calendar of the type referred to and in which the indicia will be so arranged that by the movement of only one of the disc members, the desired year may be brought into view and into register with the month desired, and also the consecutive days of the week will be brought into register with the appropriate ordinals of the days of the month.

Another object of the invention is to provide means of simple, inexpensive construction that can be folded into compact form and which will serve in an emcient way to support the disc members for display and convenient adjustment.

The invention, with other objects and advantages thereof, and the particular construction, combination and arrangements of parts comprising the same, will be understood from the hereinafter contained detailed description when considered in connection with the. accompanying drawings forming part hereof and illustrating one embodiment of the invention.

' In the drawings:

Fig. 1 is a front elevation of a multiple year calendar constructed in accordance with the present invention;

Fig. 2 is a rear elevation of the same with the rear leg member of the easel folded against the frame thereof;

Fig. 3 is aside view;

Fig. 4 is an elevation of the back disc member;

Fig. 5 is a similar view of the front disc member;

Fig. 6 is a front elevation of the easel without the disc members.

While a preferred embodiment of the invention is illustrated in the drawings, it will of course be understood that minor changes and modifications may be made in the particular construction shown, and the invention may be embodied in other forms as will appeal to those skilled in the art and falling within the scope of the appended claims without departing from the spirit of the invention.

Referring to a detailed description of the particular embodiment of the invention illustrated 2 in the drawings, the calendar disclosed is for the years 1945 to 1999 inclusive. The construction shown comprises disc members I- and 2 disposed one upon the other. The back disc member 2 bears the ordinals of the years referred to arranged in a circle in radially disposed columns 3, those years in which the order of the days of the month with reference to the order of the days of the week are the same in corresponding months, being grouped in the same columns.

The back disc 2 also has thereon in a circle inwardly of the columns 3 of years, the designations of the consecutive days of the week repeated four times and spaced according to the spacing of the radial columns of years.

The front disc member I is of less diameter than the back disc member 2, an annular space 4 being provided on the back disc for a decorative design or advertising matter. disc member is provided with a segmental shaped opening 5 in its lower part and below said opening has thereon a table of the ordinals of the' days of the month, said opening 5 exposing at one setting the designations of seven days. The front disc member also has an arcuate shaped opening 6 in its upper part exposing at one setting several. of the groups of years, and having below the opening 6 designations of the, months of the year grouped in radial columns to. register with the year columns 3, the months of January and February being repeated for use for leap years. These two months are indicated in the drawing by being underscored. In practice, they will be printed in red or somev other distinctive colored ink.

Means is provided for pivotally connecting the.

disc members I and 2 together at their central justment of the front disc relatively to the back disc for setting the calendar for the year and month desired. The supporting means is in. the

form of an easel comprising a frame having an upper straight fiat section 8 and outwardly curved flat leg portions 9 and l 0 diverging downwardly from the lower end of the upper section 8 in the plane thereof, and a rear flat leg member ll hinged at its upper end to the upper end of the upper frame section 8. The hinge connection between the rear. leg member H and the upper frame section is formed by spaced eyes l2 and 13 on said frame section, an eye M at the upper end of the leg member, and a pintle pin IS, the eyes 12 and [3 being formed integral with the upper frame section 8, the leg member II The front being foldable against section 8 when the calendar is not in use.

The disc members I and 2 are each provided with a central aperture, the apertures being designated Ia and 2a. The disc members are pivotally connected together and to the upper straight section 8 of the frame by a bolt I6 and nut H, the bolt extending through the central apertures of the disc members and through an aperture in the upper frame section 8, the nut II being disposed at the rear side of said upper frame section. The rear leg member II, as shown in Fig. 2 of the drawings, is provided at its upper part with a circular enlarged portion IIa that has an opening I Ib to accommodate the nut I'I when the leg member is folded inwardly against the upper frame section 8, the circular enlarged portion serving as reinforcing means for the leg member.

In the use of the calendar the front disc member I is rotated until the year required shows through the opening 6 in the upper part of the front disc and into register with the month desired, this adjustment also bringing the consecutive days of the week into register with the appropriate ordinals of the days of the month, the adjustment of the calendar being accomplished by the movement of only the front disc member I. In instances where the adjustment of the front disc member I provides for the display of the indicia much to the right or left of the vertical longitudinal axis of the calendar, as will be understood, the two discs may be rotated together to position the indicia displayed to substantially coincide with the vertical longitudinal axis of the calendar. The front disc member I is provided on its front face with a knob I8 by which the same may be conveniently adjusted.

, The easel and also the disc members are formed of sheet metal, plastic or any other suitable material.

It will be noted that by the particular construction and arrangement of parts hereinbefore set forth, a multiple year calendar is provided thatwill be readily understood and can be easily operated. The supporting easel is of simple construction, can be folded into compact form, and will function efliciently to support the disc members for display and convenient adjustment. The parts can be easily assembled and the device as a whole can be produced at small cost.

What I claim is:

1. A calendar including a pair of discs bearing indicia and arranged one upon the other, said discs each being provided with a central aperture, and an easel comprising a frame having an upper straight fiat section and flat leg portions diverging downwardly from the lower end of said upper section in the plane thereof, and a rear leg member hinged at its upper end to the upper end of said upper straight section, and means pivotally connecting said discs together and to the upper frame section with the discs disposed at the front side thereof.

2. A calendar including a pair of discs bearing indicia and arranged one upon the other, said discs each being provided with a central aperture, and an easel comprising a frame having an upper straight flat section and flat leg portions diverging downwardly from the lower end of said upper section in the plane thereof, and a rear leg member hinged at its upper end to the upper end of said upper section to fold against the rear face thereof, a bolt pivotally connecting said discs together and to the upper frame section with the discs disposed at the front side thereof, said bolt extending through the apertures in the discs and through an aperture in the upper frame section, and a nut on the bolt at the rear side of said upper frame section, said rear leg member having an enlarged reinforcing portion intermediate its ends provided with an opening to receive said nut when the leg member is folded against the upper frame section.

3. A calendar including a pair of discs bearing indicia and arranged one upon the other, said discs each being provided with a central aperture, and an easel comprising a frame formed from a continuous piece of sheet material, said frame having an upper straight flat section and outwardly curved flat leg portions diverging downwardly from the lower end of said upper section in the plane thereof, and a rear flat leg member formed from sheet material and hinged at its upper end to the upper end of said upper frame section to fold against the same, a bolt pivotally connecting said discs together and to the upper frame section with the discs disposed at the front side thereof, said bolt extending through the apertures in the discs and through an aperture in the upper frame section, and a nut on a bolt at the rear side of the upper frame section, said rear leg member having an enlarged circular reinforcing portion in the upper part thereof provided with an opening to receive said nut when the rear leg member is folded against the upper section of the frame.
